I think there is 10GbE link reported in Windows gplpv 0.11.0.322 driver. Let say I have two virtual Windows running on XEN and they are in bridge with 1GbE physical NIC. Will the Windows talk to each other on 10GbE thru the bridge? What should I do to give them 10GbE access to local samba server? -- Pavel Mateja _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
